I'm glad to hear you're pleased with it's performance!
I quickly Googled UNRAID's support for touch displays and it does, sorta kinda.
UNRAID can support touch monitors, but it requires some setup,
says a Facebook discussion. You'll need to install a desktop environment on your UNRAID server and then connect the touch monitor to the server,
explains a Facebook discussion. Once connected, you can then use a web browser on the desktop environment to access the UNRAID interface,
according to a Facebook discussion.
does the screen have a battery? if it does, that's why the power requires a long press to turn on or off. if it was a simple single press, any bump would turn it on and kill the battery. I have the cheap ad entry level 15.6" Arzopa with a battery and it takes a long time to turn on / off as well. I use it as a secondary screen to the Dell G15 I bought from you and the only really annoying thing about it is WIndows recommends a different scaling percentage vs. the laptops display. so while everything is the same resolution / aspect, text / icon size, etc aren't matched. it's weird jumping between the two sometimes.
